摘要： Cutting forces change regularly with the variations of cutter angle and cutting parameters. In this paper, a new modeling method was proposed for predicting cutting forces in side milling of aluminum alloy. It was established on the basis of a mechanistic model, where the coefficients of cutting forces were described as the power functions of instantaneous undeformed chip thickness. Cutting tests were carried out in the milling center HSM500 for calibrating the parameters in the model, and the model is applicable over a wide range of cutting conditions. A series of experiments were conducted to validate the effectiveness of the model. It is shown that the predicted cutting forces agree well with the measured ones, with the mean accuracy of nearly 6%.
